Heating fixture

Abstract

An improved heating fixture, wherein the support means upon which a workpiece to be heated is mounted, is a vitreous carbon plate. The use of a vitreous carbon support plate significantly reduces the time required to heat and cool the support plate and a workpiece thereon.

We claim: 
     
       1. In a heating fixture comprising an energy source, support means disposed to absorb energy from said energy source for heating said support means and a workpiece thereon, and   an enclosed support frame including mounting means for said energy source and said support means; wherein the improvement comprises a non-porous, ridid, heat conductive, vitreous carbon plate ground to a desired degree of flatness as the support means and being mounted on said support frame for said energy source.   
     
     
       2. The article of claim 1 wherein said energy source is a radiant heater. 
     
     
       3. The article of claim 2 wherein a reflector is mounted on said support frame, such that energy from said energy source emitted away from said support means is reflected back toward said support means.
